This primary difficulty is overcome by locating o. cylindric sleeve adjacent. to the iorwerd; end of the drinn, by en adjustment of Wl'iich sleeve the :in ler interval between the adjacent edges "e slee/ye and the drum is edepted to be l or `closed at will, thus positively con @the 'amount ol outside en? which een jiththeges et the forwerd end of the "druid :When :L controlling sleeve is used, er is 'preferably sufliciently en` ,het the whichris discharged freni.

To overcome this supplemental diflieulty, the sleeve is ex tended forti-'enh by ineens of!" en :u `:estable tube, into e tapered rin,o iocetcd in and through the Well of the furnace, the forward end of the tube being approximately large es the Vforwerd end smaller end of the ring, whereby zi eontrouebie sinount of sir is 'Specification of Lettere Patent. eppiicauml ered muy 2a,

l drewn through the annuler intervel between the er d of the tube and the ring, which mixes 1 with the Home es it emerges from the tube,

end serves to cause e complete combustion of all the free ges which remains 'therein after the initial coinlmstion.

The invention, thus described in general terms, is illustrated in the accompanying drawings, forming part hereof, in Which- Figure 1 isa. longitu(linebvorticel section of the burner in connection with the Well of the furnace; Fig. 2, e front elevation of the ges drum; Fig. 3, a front elevation of the tc.- pered ring showing the extension tube in cross section; and Figa-4, e. fragmentary side elevation ofthe ges drum showing e modiiied form of the edjusting sleeve.

Simile-r numerals refer to similar parte throughout the drawings. i Y

The burner is composed of the cylindre drum l, the adjusting sleeve 2, the extension tube 3 and the tepered ring e. In the axial line ci? the drum is provided the air tube 5 which extends through from. the rear end well to the forward end wall; end on the rear end of the drinn is provided the gate v6, which by a partial or complete closurev over the end of the axial tube, controls or coins pletely. stops the passage of sir therethrough. ln the forwerdwell ot' the drum is provided .the series of enertures 7 through which ges is adapted to )e discharged from' the drum; and the supply of ges is reoeived throu h the inlet pipe 8 and is regulated by the orc inary velue 9, which inlet pipe also preferably constitutes the support for the drum. The edjusting sleeve 2 is telescoped on the rear end of the extension tube 3 Withmreference to which it is adapted to he inoved' endwise, preferably by Ineens of longitudinal slots l0 inthe sleeve end guide posts in the form of the screws ll on the tube `adopted to operato in the slots. The extension tube is axially supported and adapted to be adjusted endwisc in the tapered ring, 4, preferably by ineens of the longitudinal interna-l ribs l2 in the ring.

The parte ere so errengedthet the sleeve walls of the ring. THe adjusting sleeve may be made of larger diameter than the as drum, in which event the rear end is provil ed With the inturned flange 13 which is `adapted to abut against the edges of the forward end' of the drum to completely close the interval between the sleeve and the druin if such closure is desired, which form of construction is illustrated in Fig. l or, when the adjusting sleeve, as 2a, is of equal or less diameter than the exterior diameter of the gas drum, the rear end of the sleeve is preferably proided with the flaring flange 14, as'shown in lit is evident that when gas is discharged through the apertures in the forward end of the drum, the suction caused by its current will draw a certain amount of air through the axial tube, and that by a suitable adjustment of the sleeve with reference -to the drum, a sufficient additional amount of air will be drawn through the annular interval between the drum and the sleeve to cause an initial combustion in the sleeve; and that by a suitable adjustment of the tube with reference to the tapered ring, the current of the initial iiai'ne will draw a suilicient amount of air through the interval between the tube and the ring to cause a combustion of all the free gas which may be contained in the ilaine, thereby accomplishing a complete coinbustion, and producing the maximum heat from the saine. w

The extensible tube between the gas drum. and the tapered ring, can also be employed to control the position and character of the ila'nie For this purpose the druin-sleeve .interval is partially or entirely closed and thc air-tube gate is adjusted to prevent the inixture of enough air with the gas 'in the sleeve to caus'e an initial combustion therein, and

A the combustion then takes place either in the forward end of the extension tube or lat a point in front of the same, according to the relative additional amount of air which must be drawn through the tube-rin interval to cause combustion'. By great y constricting the druni-sleeve interval and the drum air-tube, and correspondingly enlarging the tube-ring interval, a comparatively long flame can be projected Well forward from the y endI of the extension tube.

What I'claim as my invention, and desire to secure by Letters Patent, isf

1 1.1'A gas through tube therein and adapted to discharge gas at its forward end around the tube, an adjustable sleeve adjacent to the forward end of the drum, a tapered ring in front ol' the sleeve, and a second tube extending fioin the sleeve into the ring, whereby air drawn through the drum tube and through the drum-sleeve interval is inixed' with the gas, and additional air is drawn .through the tube-ring interval to cause coinplete coinbustion.

2. A gas burner including a drum having a through tube therein and adapted to dis' charge gas at its forward end `around the tube, a sleeve adjacent to the forward end ol" the drum, a tapered ring in front of the sleeve, and a second tube extending from the sleeve urner including a drum having a into the ring, whereby air is mixed with the gas in the sleeve and additional air is drawn through the tube-ring interval to cause coin'- plete combustion.

3. A gas burner including a druin'v adapted te discharge gas and air at its forwardeiid, a

tapered ring in front ol the drum, and an intervening extensible tube having its-:rear

through tube therein and adapted to dis-v charge gas at its forward end around the tube, an adjustable closure for the tube, and an adjustable sleeve in front of the drum, whereby controllable amounts of air from 8,0 Y end adjacent to the drum and its forward i theA tube and from the rear end of the`sleeve j are mixed with the gas in the sleeve.
